r such a manner that little or no grain is lost during the operation.

This and other objects I obtain by the novel construction andarrangement of parts as shown in the accompanying drawings in whichFigure l is a side elevation of the complete machine. Fig. 2 is a topplan view of the same. Fig. 3 is an enlarged rear elevation. Fig. 4t isa view of the operating mechanism of the clutch A. Fig. 5 is a sectionshowing the locking mechanism of the box 10.

The main frame 1 is composed of side pieces 2 and 3 and front and rearcross pieces 4% and 4: and is supported by the drop axle 5 carrying uponstub shafts 6 and 6 the wheels 7 and 8 and by caster wheels 9 mountedunder the rear of the side pieces 2 and 3 Attached by bearings to theforward end of the frame 1 is a cross shaft 22 fitted at the ends withforwardly extending arms 23 and 24 which. are adapted to turn saidshaft. A cross bar 25 is permanently secured to the arms in a closure ofthe shaft, said cross bar having fingers or sweeps 26 having their rearends freely swung on the shaft 22.

Attached to the arms 23 and 24: are flexible connections 55 which passup and over pulleys 56 attached to the upper ends of uprights 28 and 30thence downwardly and rearwardly, one to the crank 53 formed by theupturning of one end of the cross shaft 52 carried by bearings on theunder side of frame 1, the other to the actuating lever 5 attached tothe other end of the shaft 52. It will be seen that when the lever 54:is actuated as from the seat 51, the lingers 26 are raised. Attached tothe upright 28 at are the hangers 34 supporting the rotatable shaft 33.The shaft carries a gatherer 36 constructed from a rod bent to form anopensided rec-tangle. The ends carry weights 37 7 and the cross piecethe roller 38. The cross shaft together with the gatherer are rotated bymeans of a sprocket 39 on the end of the shaft 33 which is driven by thechain 43 which isin turn driven bythe large sprocket wheel 40freelymountcd on the stub shaft 6 and provided with a female member ofthe clutch A the male member of which is fixed to the hub of the wheel8. Means for shifting the sprocket 40 are provided in the pivoted bellcrank lever 44, carried by a pair of brackets 45, which engages achannel 46 .on the inside of the sprocket d0. The clutch A. is heldnormally open by the spring 50 connected to the lever is and to anangularly disposed brace rod between the uprights 25) and 30. A pivotedlever 47 connected to the free end of the bell crank and attached to theslidably mounted trip rod 4:8 terminating at the end in the foot piece49 affords means for operating the bell crank. A receiving box 10 havinga bottom12, a rear gate 15, upright sides 13 and 14k and'an open frontend. The gate 15 is carried by'a' cross shaft 16 mounted in brackets 17secured to the bottom of the receivingbox and is held closed by an arm18 which arm is engaged and held in position by a'pivoted crank 19fitted with an extended handle 20. Hand pieces 21 secured permanently tothe box and extending rearwardly therefrom are utilized to return thebox'to position after being dumped as described below.

The means for dumping the box comprise a drum 65 loosely mounted on thestub shaft 6 and provided with a female member 66 of the clutch 13adapted to engage with a male member 67 attached to the hub of thesupporting wheel 7. Attached to the drum 65 is a cable 71 passingupwardly and over a pulley carried by the arm 69 attached to the upright27. From the pulley the cable passes down and is attached to an anchorbar 68. Means is provided for throwing the clutch B, which is normallyheld out of position by the spring 80, passing between the bell crankand an angularly disposed bracing bar 81, into engagement, comprisingthe bell crank 72 and bracket 73 similar to those described in clutch A.The bell crank has one end forked which end enters the channel 74located at the in nor end of the drum. A pivoted lever 75 has the upperend connected to the bell crank and the lower end pinned to a link 76connected to the cranked end 77 of a cross shaft 78 rotatably mounted inbearings carried by the under side of the frame.

The cross shaft is fitted with a lever 7 9 located within convenientrange of the drivers seat.

The construction just described allows the driver to upset the boxhimself without the help of an attendant. It will be seen that once theclutch B is engaged the drum will wind on the stub shaft and cause thecable to pull up on the anchored arm with the result that the receivingbox is dumped backwardly.

By means of a catch 57 pivotally secured at 58 to the main frame adaptedto engage with a plate or bracket 59 the box is locked into position.Means for unlocking or releasing the box comprise a link 60 connected tothe catch piece 57 above the pivot point and passing rearwardly to thelower I end of a downturned crank 61' at one end of a cross rod 62rotatably mounted in bearings carried by the cross member tsupplied atthe opposite end with the lever 63 adjoining the seat. By means ofsprings G l passing between the rear end of the hub 60 and the crossmember 4 of the frame the upper end of the catch piece is kept normallyback so that it will automatically engage with and catch the bracketwhen the receiving box returns to place after being dumped.

The traction means consist of a cross rod 82 held somewhat in advance ofthe fingers by the supporting bar 83 secured permanently to the uprights27, 28 29 and 80. The draft animals are hitched on the outer sides ofthe bars 83 between rings on the cross bar 82 and draft bars 85extending outwardly from the sides of the main frame.

When the machine is in use, the sheaves are initially picked up by thefingers and are slid, as the machine advances toward the box, althoughthey may not be initially delivered to the box. If not the driver throwsthe clutch A so that the gatherer turns and pushes the sheaves back intothe box, the roller 38 engaging them about the center or slightly below.After a load has been collected the machine is driven to the place whereit is to be unloaded the driver previously raising the forks by means ofthe lever 54 so that they will clear the field. Arriving at the pointwhere the load is to be dumped the attendant grasps the hold piece :20and releases the crank from the bar 18 which allows the gate to swingopen. The driver then releases the catch piece 57 and the attendantimmediately dumps the load by pressing down on the hand pieces 21. Ifdesired the driver can dump the load by throwing the clutch B when themachine is still in motion. As the driver returns for a new load theattendant throws up and locks the gate closed.

What I claim as my invention is 5- 1. The combination with a main frameadapted to be drawn along the ground, and fingers or sweeps carried bythe front of the frame and adapted to pick up material off the ground,of a receiving box pivotally secured to the frame having the forward endarranged to receive material passed over the fingers, and the rear endopen, and a releasable gate normally closing the rear end of the box, asand for the purpose specitied. 1

2. The combination with a main frame mounted on a suitable carriage andcaster wheels and a receiving box pivotally secured to the frame andarranged to dump rearwardly, of means actuated by one of the carriagewheels for automatically dumping the box, as and for the purposespecified.

3. The combination with a main frame mounted on a suitable carriage andcaster wheels and a receiving box pivotally secured to the frame andarranged to dump rearwardly, of a rotatable drum adjoining one of thecarriage wheels, engageable clutch members carried by the drum and thecarriage wheel, means for engaging the clutch members, a pulleysuspended above the frame and free of the box, and a cable secured tothe drum and to the box passing over the pulley, as and for the purposespecified.

4. The combination with a normally inclined main frame mounted forwardlyon carriage wheels and rearwardly on caster wheels, and a forwardlyinclined receiving box carried by the frame and pivotally secured to thesame, of a bracket located on the under side of the box at the front, apivoted spring pressed catch piece carried by the frame and normallyengaging the bracket thereby locking the receiving box to the frame andmeans controlled by a lever for releasing the catch piece from thebracket to free the box to dump, as and for the purpose specified.
